SPRING-OILER.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed April 9, 1917. Serial No. 160,774.

To all whom it may concern.

Be it known that I, IVILLIAM H. BROWN, a citizen of the United States ofAmerica, and a resident of Cleveland, county of Cuyahoga, and State ofOhio, have invented certain new and useful Improvements inSpring-Oilers, of which the following is a full and clear specification.

The object of this invention is to provide an extremely simple oilingdevice which may be readily attached to the usual rebound clip or to aspecial clip attached to the spring, the construction being such thatthe appliance may be attached to springs of various widths.

In the drawing Figure l is a plan view of a portion of a leaf springshowing the application of my device thereto;

Fig. 2 is a side elevation thereof;

Fig. 3 is a section through the oil receptacle on the line 33 of Fig. 1;

Fig. at is a horizontal section through the oil receptacle on the line4-4 of Fig. 2, looking upwardly at the under side of the cover; and

Figs. 5 and G are perspective views of modifications.

Referring to the drawing annexed, a designates the usual rebound clip,and b designates the side arms of a spring wire bail whose free ends areanchored to the upper end of the rebound clip by being provided witheyes 0 which are clamped against the outer faces of the upright bars ofthe rebound clip by means of the head and nut, respectively, of thepivot bolt (Z of the rebound clip. The connecting member a of the bailcarries the oil receptacle 7, which, in the present instance, is acircular box having fitted down over its upper open side a cover 9,coincident openings it being formed in the cover and the body of the boxfor the egress of oil. these openings being located at a point above thenormal level of the oil. so that the feed of the oil through theopenings will be a splash feed. The oil receptacle is pivotally mountedon the cross-bar e by having said cross-bar extend through the openingsh from one side of the box to the other. A suitable filling opening isprovided in the cover of the receptacle and this opening is keptnormally closed by means of plate i provided with a convexupwardly-projecting part j which fits up into the filling opening, saidplate being formed of bent spring metal having its end riveted to theunder side of the top at 70. I

It will be observed that the jouncing action the spring receives whilethe vehicle is in motion on the road will agitate the oil in thereceptacle sulliciently to splash the oil into the openings h, whencethe oil will run down the sides of the receptacle and the side edges ofthe spring, from whence it will seep into spaces between the contactingfaces of the leaves of the spring. Preferably, the width of the oilreceptacle is such and the oil exit openings h are so arranged that theoil will run directly off the sides of the re- 1 ceptacle onto the sidesof the spring, Whereby very litle, if any, of the oil will be allowed tocollect on the top side of the spring. It will be observed that it isdesirable that the receptacle shall rest upon the spring, so as not onlyto be directly jounced by the action of the spring, but also to deliverthe oil directly from the sides of the receptacle onto the sides of thespring. The holes h are, of course, slightly larger than the diameter ofthe connecting bar 6, so as to allow free escape of the oil. It will beobserved also that in the specific construction shown, the bail servesto lock the cover on the receptacle, thereby rendering additional orextraneous fastening devices unnecessary.

It will be observed also that a very important feature of the form ofthe device shown in Figs. 1 to 4 lies in the idea of connecting the oilreceptacle to the spring by means of a pair of bars which may be readilybent inwardly toward each other or outwardly away from each other,thereby permitting this device to be readily adapted for attachment tosprings of various widths. This construction also, as will be seen.lends itself very nicely to the attaching of my device to the usualrebound clip of the spring, it being possible to attach the device tothe clip by simply inserting the usual bolt cl of the clip through theeyes 0 at the ends of the attaching arms.

' It will be observed from an inspection of Figs. 5 and 6 that I mayanchor the receptacle by means of a single side arm or member instead ofa pair of such members. as shown in Figs. 1 to at, inclusive. In thiscase, it will be desirable to make the anchoring arm a little stifferthan in the form of the device where two of such arms are employed. Asshown in Fig. 5, this arm may be of stiff wire, or, as shown in Fig. 6,it

may be a flat plate which is attached to the receptacle by riveting itto the exterior of the receptacle. When this flat plate or bar is used,it will be desirable to provide the plate with a depending piece Zimmediately in line with the oil-discharge opening, so that the oil willrun down over the exterior of the plate and thence to this dependingpiece and thence to the side of the spring, thus constituting with theanchoring memher a means for delivering the oil from the receptacle tothe side of the spring. This oil delivering or conducting device may beembodied in the form of device shown in Figs. 1 to a by attaching itdirectly to the cup, this being shown at Z in Fig.

The nature and scope of the invention having been thus indicated and itspreferred embodiment having been specifically described, what is claimedas new is:

1. The combination with a leaf spring of an oil receptacle resting onthe top side thereof, and means for anchoring the receptacle in positionon the top side and in contact therewith, said receptacle being providedwith an oil exit at a point above the normal level of the oil, theanchoring means embodying a pair of laterally-bendable arms anchored atone end tothe usual clip on the spring and connected at the other end tothe opposite side walls of the receptacle at a point above its bottom.

2. The combination with a leaf spring of an oil receptacle resting onthe top side thereof, and means for anchoring the receptacle in positionon the top side and in contact therewith, said receptacle being providedwith an oil exit at a point above the normal level of the oil, theconnection to the receptacle embodying a bar extending through a hole inthe side wall of the receptacle body above its bottom.

8. As a new article of manufacture, an oil cup having an exit opening atapoint above the normal level of the oil and provided with a pair ofside attaching arms connected to the receptacle above its bottom andbendable toward and from each other,

the free ends of the arms being provided with eyes, and a pivot memberextending through the eyes to connect the arms to the spring to beoiled.

4;. As a new article of manufacture, an oil cup provided with a cover,an oil exit opening being provided through the cover and the body of thecup at a point above the normal oil level, and a pair of attaching armsconnected at opposite sides of the cup through said oil openings.

5. As a new'article of manufacture, an oil cup provided with a cover,the cover and the body of the cup being provided with coincidentopenings at opposite sides of the cup, a bail having side arms bendabletoward and from each other, and a cross-bar extending through theaforesaid openings to thereby pivotally connect the cup to the bail andlock the cover on the cup.

6. As a new article of manufacture, an oiler for multi-ply leaf springsembodying an oil cup having a discharge opening therein above the normallevel of the oil and provided with an anchoring member fastened at oneend to the side wall of the receptacle and having its free end providedwith a pivot bolt-receiving eye.

In testimony whereof I hereunto afiix mv signature.
